摘要:
芽孢杆菌(Bacillus sp.)是一种重要的植物病虫害生防菌。为筛选防治牛蒡(Arctium lappa L.)南方根结线虫(Meloidogyne incongnita)的高效芽孢杆菌,并初步研究其生防机制。从牛蒡根结线虫病抑制性土壤中筛选出含有芽孢的细菌72株,通过检测不同菌株发酵滤液对南方根结线虫卵孵化的抑制作用和对二龄幼虫的致死作用,筛出孵化抑制率>75%和二龄幼虫校正死亡率>70%的菌株4株,然后进行盆栽灌根试验。结果表明,菌株LB-16发酵滤液处理的根结指数最小、防治效果最大。通过对菌株形态特征、生理生化特性和16S rDNA测定,将菌株LB-16鉴定为和短短芽孢杆菌(Brevibacillus brevis)亲缘关系接近的芽孢杆菌。通过不同浓度菌株LB-16发酵产物作用于南方根结线虫二龄幼虫,测定其总糖含量、总蛋白含量、乙酰胆碱酯酶活性、过氧化氢酶活性和羧酸酯酶活性等,研究短短芽孢杆菌防治南方根结线虫的机制。结果显示,菌株LB-16发酵产物浓度越大,南方根结线虫的总糖含量、总蛋白质含量、乙酰胆碱酯酶活性、过氧化氢酶活性和羧酸酯酶活性降幅越大,干扰线虫的正常代谢,从而达到致死目的。研究结果为探明芽孢杆菌杀线虫的作用机制提供了理论支撑,为更好地开发芽孢杆菌杀线剂提供了依据。
